Differentiable Co-Design of Ultrasound Probe Geometry and Acquisition for Plane-Wave Imaging
Somashekhar Dehury, Mahesh Raveendranatha Panicker
Ultrasound image quality depends on both the probe geometry and the transmit and receive processing, but engineers usually design the two separately. Physics-based simulators (Fiel…
Physics-Grounded Objective-Conditioned Deep Beamforming for Adaptive Resolution-Contrast Control in Plane-Wave Ultrasound Imaging
Gopika Gopikrishnan, Mahesh Raveendranatha Panicker
Plane-wave ultrasound enables ultrafast imaging but remains constrained by a receive-aperture-dependent resolution- contrast trade-off. Fine structures benefit from high spatial re…
